Abstract
The precision measurement of the mass of the boson is an important goal of the Fermilab Tevatron and the CERN Large Hadron Collider (LHC). It requires accurate theoretical calculations which incorporate both higher-order QCD and electroweak corrections, and also provide an interface to parton-shower Monte Carlo programs which make it possible to realistically simulate experimental data. In this paper, we present a combination of the full electroweak corrections of {\tt WGRAD2}, and the next-to-leading order QCD radiative corrections to production in hadronic collisions in a single event generator based on the {\tt POWHEG} framework, which is able to interface with the parton-shower Monte Carlo programs {\tt Pythia} and {\tt Herwig}. Using this new combined QCD+EW Monte Carlo program for production we provide numerical results for total cross sections and kinematic distributions of relevance to the mass measurement at the Tevatron and the LHC for the processes . In particular, we discuss the impact of EW corrections in the presence of QCD effects when including detector resolution effects.
